Product Description
The DAC-633 Delta Application Controller is a Native BACnet
Application Controller that communicates on an RS-485 LAN
using the MS/TP BACnet protocol. The controller is designed
for a wide range of applications with small local I/O
requirements. Both firmware and controller databases are
loadable over the network.
With 6 inputs, 3 analog outputs and 3 binary triac outputs, the
DAC-633 is suitable for controlling various packaged units and
other equipment with small I/O requirements. As the controller
is completely programmable, GCL programs and BACnet
objects can be tailored to the specific application.
Important Information
ORCAview OWS and controller firmware must all be of the same version number to be
compatible. When upgrading any of these products from older versions (i.e. 3.22 or 3.30), you
must upgrade all the remaining products. Exception: UL 864 model, DAC-633-UL864 can be
used with V3.33 and V3.40 firmware.

UL864 Specific Considerations
Wiring to and from the device shall be through power-limited circuits.
Use only Core Components transformer, Model No. 120-024-100-2TF-CB, by Lectro
Components Inc. to power the device. (Delta Part # 440008)
Use only UL Listed Class 2 Power Supplies for auxiliary field devices.
Use only UL Recognized Ethernet Switch, 571-580, by Siemens for Smoke Control Systems
that utilize Ethernet communications.
Impedance value for which ground faults are detected is zero ohms.
Cautions or Warnings
This controller is an Electro-statically sensitive device. Proper ESD protection (ground strap)
should be used when installing this product so that damage to the product does not occur.
Equipment damage or loss of data may occur if these procedures are not followed as
specified.
Installations requiring CE conformance: All wiring for CE rated products must use an extra
low voltage (SELV) or protective extra low voltage (PELV) transformer. Use safety-isolating
transformers, (Class II transformer) per EN61558. The transformer must be rated for 100%
duty cycle.

Mounting
The DAC-633 includes a plastic enclosure that can be quickly mounted with two screws (not provided). This
controller should be mounted in an appropriate location within packaged equipment or another enclosure that
meets code requirements.

Controller Configuration
Derived Network Addressing
The DNA jumper comes ON by default. This allows the controller to
automatically configure a BACnet controller address. This should NOT be
removed unless you are assigning a BACnet controller number through
software. The BACnet controller number should not be confused with the DIP
switch setting, and each controller must still have a unique dip switch address
even when using software to define the controller number.
DNA
Controller Addressing
The Dip Switch is a binary switch. Each individual DIP switch represents a
unique value, which forms the controller address when added together.
To set the address, simply move the switches that add up to the controllers
desired address to the ON position.
Example: If the controller is to be address 5 on the network, set the switch
numbered 4 and the switch numbered 1 (equals 5) to the On position.
Note: Each controller on the same MS/TP segment must have a unique DIP
switch address.

Wiring General
All wiring must conform to NEC and local codes and regulations. Use earth ground isolating step-down Class 2
transformers. Do not use autotransformers. Determine supply transformer rating by summing total VA of product
and output loads.
Risk of Electric Shock or Fire
More than one disconnect switch may be required to de-energize the
equipment before servicing.
Input Class 2 Power Supplies are interconnected. Use only Class 2
sources suitable for interconnections.
All terminals are acceptable for Class 2 Circuit connections only
Use copper conductors only
Apply minimum 6.0 lb-in torque for tightening field wires into the terminal
blocks
Power
This product is designed to use a 24 VAC, Class 2 power supply. The proper specified cabling must be used.
(18 – 16 AWG, 2-conductor wire)
A single transformer may be used to power multiple controllers and/or auxiliary field devices (actuators, etc.)
provided the following conditions are met:
All devices MUST be ½ wave rectified. Mixing power between ½ wave and full wave rectified devices
will damage both the transformer and connected equipment.
The transformer is properly sized, including line losses for the total VA requirements.
Polarity is observed between controllers (with respect to 24~ and Gnd).
Each controller is grounded as shown in the diagram below. This is important to protect equipment and
ensure a common ground reference for RS-485 communications.
The transformer secondary is fused for its maximum rated load (4A max for Class 2 circuits).
Make sure to ground the controller using the ground lug that is available on the
controller.

Network Communication
The controller communicates on an RS-485 LAN using the BACnet MS/TP protocol. Refer to Delta Controls
Wiring Guidelines for further details.
MS/TP (RS-485) Wiring
For detailed information on MS/TP and LINKnet wiring refer to Delta Controls Wiring Guidelines.
The proper specified cabling must be used to ensure reliable communications. (22 AWG twisted
pair, 100-120 ohms impedance, 17 pF/ft or lower capacitance, with a braided or aluminum foil
shield.)
Controllers should always be wired together in a daisy-chain fashion. Attempting to connect them
using a starred or bus configuration will cause problems on the network.
Networks with a total length greater than 4000 ft or with more than 50 controllers require a
repeater (RPT-768).
LINKnet networks that have only 1-2 controllers, and have less then 100 ft of cable length do not
require network terminators.

Input and Output Wiring
Inputs and outputs on the DAC-633 controller follow the same general wiring requirements as other Delta
Controls products. Recommended cable types should be used as listed below. Refer to the Delta Controls
Wiring Guidelines for more details.
Recommended Cable Type
Where to Use
2 Conductor, 18 AWG, Unshielded
All output types and 4-20mA, 10KΩ, and 10V input types
2 Conductor, 22 AWG, Shielded
Inputs configured for 5V
Input Configuration
The input must be configured to accept the signal used by
the input device. Place the jumper for each input in the
correct location on the Input Type Selector Block. The
diagram to the right shows the factory default selection of
10 KΩ.
4-20mA For sensors that use a 4 to 20 mA signal.
10K For 10 KΩThermistor temperature
sensors, as well as Dry Contact binary
inputs.
5V For sensors that use a 0 - 5 VDC signal.
10V For sensors that use a 0 -10 VDC signal.
Binary Output Power Source
The binary triac outputs can be selected to use either an
internal or external power source by placing the two
jumpers in the correct locations. The diagram to the left
shows the factory default selection of External Power
Source.
Internal - 24 VAC Power is provided internally from within
the board right to the output terminals. No external
transformer is required. The associated triac outputs are
“hot” contacts. Note that the power supply should be sized
appropriately to handle the additional loading.
External - Power needs to be provided externally to the
board from a nearby transformer appropriately connected
to the output wiring. The associated triac outputs are not
“hot” contacts, except by means of the external
transformer.
NOTE - Triacs are solid-state components that are only
appropriate for switching 24 VAC. They cannot be used to
switch 24 VDC. They also have a small leakage current
and are not appropriate for “dry contact” applications.
